*p < 0.05; **p < 0.01; ***p < 0.001.Shown is (n), number of individuals; (h), haplotype diversity, (π), nucleotide diversity; (τ), mutational time since demographic expansion; (theta) the mutation parameter per sequence as observed and (theta0) prior to expansion; TSE, Time since the last population expansion; (Tajima’s D), Tajima’s statistics (1989); (R2), Ramos-Onsins and Rozas statistics (2002); (Fs), Fu’s statistics (1997); (the estimated time since expansion is only given for those clades/taxonomic units with significant population growth identified by more than one method (Tajimas’s D, R2, or Fs), using different divergence rates.
